To all 'LU/LOITI/ it ntcty concern:

Be it known that I, GUsrAv FAJEN, a citizen of the United States, and aresident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in RotaryMeters; and I do hereby declare that the following is a full, clear, andexact description thereof.

My invention consists in certain peculiarities of construction andcombination of parts hereinafter particularly set forth with referenceto the accompanying drawings and subsequently claimed, the object of theinvention being to provide simple, economical, and accurate fluid-metersof the rotary type similar to the one set forth in my application filedMarch 9,. 1905, Serial N 0. 249,188.

Figure l of the drawings represents a ver tical longitudinal section offluid-meter casing out on lines 1 1 in Fig. 2, the mechanism inclosed bythe casing being in side elevation, partly broken and partly in section;Fig. 2, a plan view, partly in horizontal section, of what is shown inFig. 1, the upper cover-section of the casing being removed; and Figs. 3and 4;, detail sectional views, respectively, represented by lines 3 3and 4 4 in Fig. 1.

Referring by letter to the drawings, A indicates the lower main section,and B the upper cover-section, of an approximately annular casing, thesesections being provided with outer meeting flanges that are boltedtogether against interposed packing. The section A of the casing isprovided with legs 7),

an inletnozzle c, and an outlet nozzle (8, these nozzles beingscrew-threaded for connection with pipe through which fluid underpressure has flow to and from the meter of which said casing forms apart. The inletnozzle has communication with a segmental trough C in thelower main section A of the casing, the passage (2, in what is shown asa thickened portion of said casing-section, being'preferably restricted,and horizontal gates D E are loose in a guide-chamber F at the upper endof the trough, this chamber being recessed at the front to obtainclearance for a rotary device hereinafter specified.

Adjacent to their forward ends the gates D E are transversely recessedfrom their inner edges to have sliding hook connection with polygonalbands G H, that are rounded at their corners and which have spoke-andhubconnection with an axle I, for which recessed bearing-lugs f areprovidedupon the inner sides of the casing-section A, pins 9 beingengageable with the lugs over the axle to hold the same in place. Thebands G H are -of the same size and so disposed that each rounded cornerof one projects midway between similar corners of the other, all thecorners being closed on their inner sides be tween the bands. The gatesthat dam the upper end of the troughC have reciprocative motion, due totheir connection with the bands G H of the rotary device, and theband-opposing edges of the recesses in said gate are beveled to reducefrictional contact with said bands.

The axle I is shown provided with a worm J by which to transmit motionto any suit able registering mechanism, a bearing or step 72, for aregister-spindle being shown in the lower section of the metercasing.

The bands G H are shown as being of approximately rectangular contour;but their contour may be approximately of any preferred polygonalcontour, and in any of their various forms they are disposed one againstthe other, so that each rounded corner of one projects midway betweensimilar corners of the other, and all of the corners are closed on theirinner sides between bands, as above specified.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A rotary meter comprising a casing having a fluid-inlet and afluid-outlet, segmental trough in the casing in communication with theinlet of same, a rotary device embodying a polygonal band that hasrounded corners and engages the trough, a slide-gate arranged in hookconnection with the band to dam said trough above said inlet, and meansin connection with the rotary device for transmitting motion to registermechan- 1sm.

2. A rotary meter comprising a casing having a fluid-inlet and afluid-outlet, a segmental trough in the casing in communication with theinlet of same, a rotary device engaging the trough and embodying a pairof polygonal bands that are rounded at their corners and set so thateach corner of one projects midway between corners of the other, theseprojecting corners being closed on their inner sides between bands,slide-gates arranged in hook connection with the bands to dam saidtrough above said inlet, and means in connection with the rotarydevice-for transmitting motion to register mechanism.

10 other and are closed on the inner side between bands; slide-gatesarranged in hook connection with the bands to dam said trough above saidinlet, and a gear element in connection with said axle for transmittingmotion to register mechanism.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of l\lilwaukee and State of WVisconsin, in thepresence of two witnesses GUSTAV FAJEN.
